I have a big thumb flash drive plugged into a TP-LINK Touch P5 router (yes
obscure router with only the original firmware release). It takes incoming
connections VIA Windows 10/11 and Samba V1 to do scheduled backups. It's
often asleep and needs to be woken up or else DOS, my backup software, and
other utilities/programs think it's disconnected.

But if you browse to it using Windows Explorer first while asleep, there's
often a delay of a couple-few seconds, then it wakes up and the backup
software will then work fine. But the backup software itself doesn't
trigger a wakeup.

A simple batch file of:

@echo off
net use
y:
cd \sqwertz-backups
@dir

DO NOT wake it up.

C:\Users\Sqwertz>net use
New connections will be remembered.

Status Local Remote Network

-------------------------------------------------------------------------------
DISCONNECTED Y: \\192.168.0.1\Volume_A1 Microsoft Windows Network

But wake it up with Windows Explorer first and then:

C:\Users\Sqwertz>net use
New connections will be remembered.

Status Local Remote Network

-------------------------------------------------------------------------------
OK Y: \\192.168.0.1\Volume_A1 Microsoft Windows Network

What other commands can I put in a batch file or utility can I call just
before the backup to wake up the router's drive and WAIT for it to be awake
before it exits and the backup proceeds?

I assume the router's USB driver firmware is putting it to sleep and SMB
doesn't trigger a wakeup? I have no control over that.
